Patent number: 9609348Abstract: Video analytics systems and methods are described that typically comprise a video encoder operable to generate macroblock video analytics metadata (VAMD) from a video frame. Functional modules receive the VAMD and an encoded version of the video frame is configured to generate video analytics information related to the frame using the VAMD and the encoded video frame. The downstream decoder can use the VAMD to obtain a global motion vector related to the frame, detect and track motion of an object within the frame and monitor a line provided or found within the frame. Traversals of the line by a moving object can be detected and counted using information in the VAMD and the line may be part of a polygon that delineates an area to be monitored within the encoded frame. The VAMD can comprise macroblock level and video frame level information.Type: GrantFiled: August 28, 2014Date of Patent: March 28, 2017Assignee: INTERSIL AMERICAS LLCInventors: Fang Shi, Jin Ming, Qi Wu, Fan You, Kai Bao

Publication number: 20120057629Abstract: Video encoders, systems and methods are described that characterize video encoding processes using a ?-domain deviation metric. The deviation metric represents a weighted difference between actual non-zero coefficients and the expected non-zero coefficients, the actual and expected coefficients corresponding to quantization of a macroblock in a video frame during video encoding of the frame. The deviation metric is used to adjust the video encoding process to obtain an optimized encoding bit rate for a desired video encoding quality by selecting a quantizing parameter based on a normalized value of the deviation metric. The quantizing parameter can be selected from a table indexed using the deviation metric.Type: ApplicationFiled: September 2, 2011Publication date: March 8, 2012Inventors: Fang SHI, Biao Wang, Qi Wu, Fan You, Kai Bao

Patent number: 6499087Abstract: A multiple agent system providing each of a plurality of agents, i.e., processors, access to a shared synchronous memory. A super agent is preferably that agent from among a plurality of agents which accesses a shared synchronous memory most frequently. The super agent has direct access to the shared synchronous memory, without negotiation and/or arbitration, while the non-super agents access the shared synchronous memory under the control of an arbiter-and-switch. Open windows are generated when the super agent is not, accessing the shared synchronous memory. The non-super agents can be allowed interim access to the shared synchronous memory even, before the super agent terminates ownership of the shared synchronous memory.Type: GrantFiled: June 9, 1998Date of Patent: December 24, 2002Assignee: Agere Systems Guardian Corp.Inventors: Jalil Fadavi-Ardekani, Bahram Kermani, Walter G.
